AutoWiFi

AutoWiFi is an app that automatically connects your iPhone or iPod Touch to your favorite web-authenticated hotspots by saving your username and password and sending it to the hotspot provider when needed.

Initially I programmed this utility as I was annoyed with constantly having to log into the WiFi network at the Vienna University of Technology. Once it was done I thought, hey why not upload it to the App Store for fun and see what happens. Since then over 20000 copies have been sold.

AutoWiFi uses many of the cocoa frameworks for the UI, network connectivity and web page parsing.
